Introduction: The incidence of herpes zoster (HZ) rises steeply after the age of 50 years and the number of HZ cases and complications such as postherpetic neuralgia (PHN) is predicted to increase because of the ageing population. The objective of this study was to estimate the cost-effectiveness of recombinant zoster vaccine (RZV) compared with no vaccine for the Japanese population aged ≥ 65 years.
Methods: A multi-cohort static Markov model with a cycle length of 1 year was used to follow a hypothetical cohort of 1 million people aged ≥ 65 years over their remaining lifetime.
We have been studying the way advertisements for medicines have been monitored by the Health, Labour and Welfare Sciences Research Grants. In the last fiscal year, we identified products that were being advertised to general consumers, such as OTC drugs and designated quasi-drugs, and made recommendations to the Ministry of Health, Labour and Welfare on the methods of advertisement. Members of our research group, including physicians, pharmacists, and consumers, pointed out that advertisements for so-called health foods and foods with functional claims were much more unregulated than those for drugs, including OTC drugs.

Methods: A multi-cohort static Markov model was developed to follow age cohorts (50-59, 60-69, 70-79 and ≥ 80 years) over their remaining lifetime. Japan-specific data inputs for the model were obtained from Japanese data sources.
Regulatory science is growing increasingly important, and the Health and Medical Strategy of the Japanese government reflects this. How regulatory science is covered in pharmaceutical education is an urgent issue. Education on regulatory science is also part of the modified version of the model core curriculum in the six-year pharmaceutical course that was introduced from 2015.

The purpose of this study was to compare, in the Japanese context, the projected health benefits, costs and cost-effectiveness of the latest generation of pneumococcal conjugate vaccines which may provide important insight into the potential public health impact of interventions in the context of local disease-specific epidemiology.
Methods: A Markov model was used to compare two vaccination strategies which involve routine infant immunization with either the 13-valent pneumococcal conjugate vaccine (PCV-13; Prevenar 13™, Pfizer, Pearl River, NY, USA) or the 10-valent pneumococcal non-typeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV; Synflorix™, GlaxoSmithKline Biologicals SA, Rixensart, Belgium) over a time horizon of 5 years from the healthcare provider and societal perspectives.
Objectives: Do antimicrobial stewardship programs (ASPs) contribute to reduction of antimicrobial therapy costs in Japanese community hospitals? To answer this health economic question, a before-after comparative two-year trial in a community hospital in the country was designed.
Methods: The study was conducted at National Hospital Organization Tochigi Medical Center, a community hospital with 429 beds. We compared six-month period before-ASP (January 2010 to June 2010) and 24-month period after ASP (July 2010 to June 2012) in primary and secondary outcome measures.
As it is an urgent issue to contain increasing healthcare expenditures, unlimited reimbursement of pharmaceuticals continues to be controversial. The objective of this study is to identify acceptable incremental cost effectiveness ratios between new and conventional therapies. Clinical study data for five statin therapies were used to indicate treatment effectiveness and incremental costs were indicated by price premiums at price listing.

In order to detect adverse events in patients at pharmacies, a questionnaire was developed to evaluate adverse drug reactions that may come from the use of pharmaceuticals. The questionnaire enabled pharmacists to assume possible adverse drug reactions while they dispense a prescription but was designed not to make patients sensitive. An investigation method was developed to detect adverse drug reactions that may be attributable to drug treatment by leading patient natural complaints while pharmacists provide drug treatment guidance to patients.

A Markov model with five health states, developed by Price in 2002, was used. 1-week transition probabilities among status of asthma management were obtained from literature and epidemiological data from public data base.

However, the results of our preliminary survey suggested a hypothesis that patients were not always satisfied with explanations provided by pharmacists upon dispensing, and therefore patient satisfaction might be enhanced if pharmacists spent more time on consultation services. The survey was conducted in 1,800 people.

In this study, the relation between the time required for dispensing and prescription details and that between the time required for instruction on drug administration and instruction details in nine pharmacies in Chiba prefecture were investigated. As a result of linear regression analysis, it was suggested that, compared with doses, the number of drug items more greatly affected the time required for dispensing.

On the other hand, it has been demonstrated that fibrate agents decrease triglyceride levels more effectively compared to HMG-CoA reductase inhibitors. A cost-effectiveness study comparing fenofibrate, a fibrate agent, and atorvastatin was therefore conducted in hypertriglyceridemia patients.

We previously showed that the amount of information available on generic drugs differs greatly from one pharmaceutical industry to another, though, on average, it is inferior to that for original, brand name drugs. This report looks at information on individual generic drug products, rather than the active ingredients contained therein.

Method: Asthma-related episodes in pre and post 6 months of FP use were derived from a survey of FP on asthma-related episodes (FINE study). Medical cost was evaluated by macro-cost estimate and productivity loss by human capital approach.
Problems associated with outpatient pharmacotherapy may require hospitalization. However, such hospitalization may be prevented if pharmacist's pharmaceutical care (PC) is given. We investigated the reasons for hospitalization in medical institutions and medical expenses were calculated.

Fifty-four cases aged>16 years with either moderate persistent asthma (step 3) or severe persistent asthma (step 4) were assessed in a retrospective survey. Participants must have been a patient at the author's clinic continuously from June 2001 and been users of SLM for more than one year.

Of these three problem areas, the state of provision of information in particular has never been objectively evaluated. We therefore sought to evaluate information according to its necessity and importance to medical practice.

There was no significant difference between the groups with regard to sex, age, incidence of complication, stage of cancer, surgical method, operative time and blood loss, length of hospitalization, the appearance of systemic inflammatory response syndrome (SIRS), changes body temperature, white blood cell count (WBC), C-reactive protein (CRP), or clinical outcome of postoperative care by a nurse during post-operation for 7 days.

In August, Pharmaceutical Society of Japan published "model core curriculums for pharmacy education" and pharmacoeconomics is included in it. As the Japanese health insurance system is composed of fee for service system and small patients' co-payment, physicians as well as patients have not needed pharmacoeconomic analysis.
